gallium: give fragment-shader texture-lod its own cap
Shader Model 3.0 is a big promise to make to the state-tracker, and for instance mobile hardware might support texture lod but not some of the other features of SM3. So let's give this its own cap for simplicity. Signed-off-by: Erik Faye-Lund <[email protected]> Reviewed-by: Marek Olšák <[email protected]>
